How to set a tag to a row in a custom adapter Android Studio Java

I am trying to set a tag to the row (or at least something in the row, preferably the row though). Then when I click on the row, I can get the tag. I thought that this is what I have to do, but the tag is always null, regardless of what I tap on.

My code example shows my attempt at setting a tag to a textview, as I have no idea how to set it to the row.

This is my getView code in my customAdapter class

int counter = 0;

@Override
public View getView(int position, View convertView, ViewGroup parent) {

LayoutInflater layoutInflater = LayoutInflater.from(getContext());

View customView = layoutInflater.inflate(R.layout.my_row, parent, false);

ViewHolder holder = new ViewHolder();

holder.name = (TextView)customView.findViewById(R.id.nameTextView);
holder.picture = (ImageView)customView.findViewById(R.id.pictureImageView);

holder.name.setText(allNames.get(position));
holder.picture.setImageResource(allPictures.get(position));

//This does not work ---> holder.name.setTag(counter);

counter ++;
return customView;
}


This is my onClickListener in a different class

listVIew.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> adapterView, View view, final int position, long l) {

Toast.makeText(getApplicationContext(), "tag is " + view.getTag(), Toast.LENGTH_SHORT).show();

}
});


Any help would be appreciated. Thanks.

Try this,

@Override
    public View getView(int position, View convertView, ViewGroup parent) {

        LayoutInflater layoutInflater = LayoutInflater.from(getContext());

        View customView = layoutInflater.inflate(R.layout.my_row, parent, false);

        ViewHolder holder = new ViewHolder();

        holder.name = (TextView)customView.findViewById(R.id.nameTextView);
        holder.picture = (ImageView)customView.findViewById(R.id.pictureImageView);

        holder.name.setText(allNames.get(position));
        holder.picture.setImageResource(allPictures.get(position));

        //This does not work ---> holder.name.setTag(counter);

        customView.setTag(Integer.valueOf(counter));

        counter ++;
        return customView;
    }
